Abstract

This research aims to describe the development process, assess the validity, and evaluate the effectiveness of an English vocabulary pocket book designed as a supplementary learning medium for students of the Building Information Modeling Design Department at SMK Negeri 2 Rantau Utara. Conducted from February to March 2025, the study employed the ADDIE model, encompassing five phases: Analysis, Design, Development, Implementation, and Evaluation. The research involved 35 Grade XI students as participants. Data were gathered through interviews, validation sheets, and pre-test and post-test instruments. The developed pocket book was validated by media and material experts, achieving high feasibility scores of 92.2% and 91.4%, respectively. The results of the pre-test and post-test showed an improvement in students’ vocabulary acquisition, with average scores increasing from 65.8 to 71.3. These findings suggest that the pocket book is a valid, practical, and effective tool to support vocabulary learning in vocational education
